Right, the homepage definitely isn't built for regular people right now. The process for getting started seems to be:

go to matrix.org > click "Try Now" > get redirected to element.io > click "Open in your browser" > allow it to use IndexedDB > create an account > start messaging

I have tiny grievances with every step of this process: matrix.org is filled with too much jargon; "try now" sounds like some kind of trial; redirections to totally different websites are scary; the relationship between Matrix and Element isn't clear; the stock photo-ish background on app.element.io is a bit tacky; asking for browser permissions on page load is rude; the account creation page makes the "edit homeserver" button fairly prominent but doesn't tell us what it does in plain language; I should have been told that you can invite people by email before I clicked "send a direct message"; adding an email to invite asynchronously pulls up a "terms of service" dialog.

There's a lot to love about Matrix, so I hope it becomes easier for people to get started with it.

I'm almost good at math. Could you enlighten me, when you say "slope", are you talking about the slope of a line as defined by "The Equation of a Straight line" [0], i.e. the "m" in "y=mx+b"?

And what do you mean by "intercept". Are you referring to the "b" in that same equation?

If that's true, in what way is that an optimization to storing "x" and "y" at each node?

My journey to releasing my first app – #1 The Idea
I appreciate your point about nothing ever being "100% due to human error", especially in regards to air travel. I recently read "The Design of Everyday Things", a book that devotes a lot of its time to discussing this same principle. We should blame the UX wherever possible before assigning any blame to the individual.
"The opportunity is to equip brick and mortar stores to compete with Amazon and Alibaba — and be better than them.”

This is fantastic. It makes sense -- get the convenience of ordering online, but with the tremendously better quality of buying from a local and known source, while also supporting your local economy and peers. I try everything I can to avoid Amazon, as there is just so much garbage, counterfeit, scammed reviews, and just sheer anti-competitive crap that it's a real sore in our world.

I would possibly argue it is ideal, even. The other two obvious alternatives is that the charity pays someone to deal with paperwork (which we wouldn't call "waste," but means even less of donations go towards the mission), or disorganized people just don't start charities and find for-profit jobs.

If you want a vibrant charitable ecosystem, letting people be imperfect about how they run their charities is a good thing.
Long term, however, it'll attract high-yield jobs. These jobs (and the people working on them) will have a high impact on employment. People who have high salaries can afford eating out regularly, Uber/Uber Eats and expensive custom made stuff. This helps the lower strata of society.
Those are high-margin value-add features.

I agree with you. I want a car that drives and nothing else.

WhatsApp penetration in India isn't necessarily bad, given the size of the country. It gives a huge leverage to the Indian government: If they say they will block WhatsApp if they go through with the planned policy change, FB won't risk losing hundreds of millions of WhatsApp users.

Or they can go passive-aggressive: Mandate the exclusive use of privacy-friendly IM platforms for government and public services. If WhatsApp isn't compliant with the privacy requirements they set, tough luck. This will bring everyone onboard to another platform, and they can then individually decide if they'll also continue to use WhatsApp.

What's your view on stuff like Sia and Filecoin? I agree with you about the lack of actual use for stuff like Bitcoin etc but the storage cost aspect of those two is interesting for sure.
Well, depends on what you compete on. Tech stack? Getting drivers? Getting customers?

Uber Eats for example cannot deliver to me, but several others can. Tech stack isn’t that expensive to build. I think it’s easy for programmers to think that the whole world revolves around tech stacks and not see how you can be innovative in getting drivers for example.
Can’t really say I’m loyal to any platform when it takes less than one min to sign up for another.

It’s the same with Amazon which is just the worst shopping experience I’ve ever encountered and slow deliveries to boot and I’m very happy they have local competition that blows them out the water.
You really want to charge where you park. Day to day you want to l2 charge your EV. Which is like a 4-12 hour process. Most people without at home charging that relay on 100% supercharging a) aren’t happy about their car and b) are toasting the battery.

Simple charging plugs at work though are a solid solution. Can get your charge in while you work.

The ones that pop to mind expose what I call "fractal communication": communication that spans across several levels of abstraction that allows people to hook into at the level of abstraction that is relevant to them.

Excerpt from https://news.ycombinator.com/item?id=25398448:

>*- Align everyone: through written communication accessible anytime by anyone. Communication should tie objectives to actions and penetrate several abstraction levels and be consumable by advisors, board members, non-technical people, technical people. Call it "fractal communication" that still makes sense from any abstration level you read it. This enables everyone on the team to chime in at the abstraction level they're comfortable with. You write an email that ties objectives on say, revenues, in a language that speaks to some, and then tie it back to specific activities, an issue in the issue tracker, and a line of code, so that everyone sees how things fit together and are intertwined. Everyone knows what to do and why they're doing what they're doing. They can come up with ideas or correct assumptions or mistakes.

I went researching pre-steamer Atlantic crossing times for a project a few years ago.

Before steam, a sailing passage averaged 10-12 weeks. However the min/max bars were huge: a badly becalmed crossing might stretch to six months (with a high risk of malnutrition en route, living off ship's biscuit and pickled meat), while the fastest sail crossing was around 12 days (a fast clipper with a very favourable wind). 2 months was the norm, and the hull loss rate meant it wasn't for the faint of heart: IIRC about 5% of ships never made it to port.

Cruiseliners should be looking at starlink to provide decent connectivity. I suspect many people may be happy

Cruiseliners aren't exactly low carbon though -- the QE2 had 1900 passengers and managed 125 feet per gallon at normal cruising speed. That works out 37mpg (us gallons) per passenger

A 777-200 is about 76mpg per passenger.

Over the 20 year service life of a car, operating costs dwarf production costs.
Wolt competes, in large part, on overall user experience.
Uber 2019 revenue $14.15 billion, divided by your estimate of 10 million cars is $1415 per car per year. I would suggest you're estimating at least an order of magnitude too high for the car count, since they can more or less operate 24x7.

That would bring the capex down below $100 billion - less than Google's cash on hand. And you'd be starting with the most lucrative cities while staggering it out, and have a very good idea of your payback by the time you've spent serious cash.

Technology and regulatory risks are high for Waymo, but capex is very manageable.

They are competing here in Berlin, against DeliveryHero (which bought foodora and other smaller deliveries).
They are both the same, except the restaurant coverage. From that I can assume they have a better b2b model.
Wolt prices are higher, even though DeliveryHero prices are already higher, including the distance extra payment for me it makes it stupid to order.
I understand that the drivers get paid more and it is obvious, but as a consumer to pay 30% more for a delivery, is insane.
Back in the day you would get FREE delivery from restaurants and even extras.
Being corona lockdown I prefer to walk and get my food.

This is not a judgement against Wolt, but against this whole delivery system.

However, currently the "third largest producer of civil aircraft, after Boeing and Airbus" (Wikipedia) is Embraer. British Airways uses the Embraer 170 for some European flights: only 76 passengers, but Embraer also sells some larger planes, up to 146 passengers.

As parent said, it is a piecewise linear interpolation, which means it is divided into line segments. Hence you don't need the parameters for the whole index, only for each segment, as the parameters are the same for each point in the same segment.

A Sustainable Startup Isn't a Successful Startup
Airliners rarely crash in cruise, so doubling the hours in cruise is likely to almost halve the crash rate per hour with no significant change in crashes per flight (and therefore per kilometer).

Maybe it makes the crew a little more fatigued on descent and approach to landing, likely partially offset by it making air travel less appealing to pax, resulting in fewer people per fatal accident.

Pallene presents an alternative to JIT compiling Lua.

Probably. Considering that the grandparent mentioned that their service is actually reliable, I wish they were available here (South Bay, SFBA).

I don't think I've even had a 50% success rate with the food delivery apps here, there's almost always an issue with the delivery. At this point it's just a toss as to whether they'll deliver according to instructions (drop the package in front of the garage), deliver to another entrance (which is further for the driver), deliver to the neighbor, call for delivery instructions, or even leave it on a fence post.

It's pretty crazy to think that on top of a 30% cut that they take from the food order, the delivery fees, service fees, tip, and other arbitrary fees (I'm almost expecting a "fee collection fee" at this point), they can't even bother providing good service.
The Apple ][ predates that problematic area and for a lot of electronics replacing the Capacitors (Condensers) is vital.

> Imagine a car sometimes driving to left if you steer right. Would you blame the driver or the manufacturer.

We don't need to imagine this. There's a car called a Tesla which sometimes unexpectedly and fatally decides to steer in a different direction, and its management invariably blame the driver. Weirdly, HNers not only generally don't want Tesla's entire management and design team to be fired, they actually tend towards defending their approach...

Edit: would love it if the people who apparently disagree could make some arguments why Tesla's fatality-inducing electronic driver support system deserves a different response to Boeing's

> First of all, there is no ‘reunite’ because Taiwan has never been united with the PRC.

There is no reintegration of Taiwan into the PRC, since it has indeed never been part of it.

But the term 'Chinese reunification' is the correct one, because China has indeed split over "unfinished" business in 1949.

In any case, IMHO this narrative is moot when discussing peaceful reunification because I can only see this having a chance of happening after the mainland has transformed into a democracy, which would probably mean that it would not be the 'PRC' anymore.
I'm aware of how accounting and banking works. Borrowing does not create money in FRB, since all loans are deposits. Unless of course, the bank creates more certificates than deposits (but don't call it fraud!), which the Fed did prior to 1971, as did many private banks prior to the Fed.

FRB always ended in bankruptcy and bank runs. A central bank was created to bail them out. And what happened? The central bank went bankrupt doing the same thing. In 1971 the US couldn't honor its foreign gold obligations – which is exactly what happens when you promise to deliver something you don't have. The US defaulted on their obligations.

Why I Didn't Open-Source My Second SaaS
Yes. Wolt couriers in my country often mention that they're treated much better than in their previous gig at <another delivery service>. Wolt has customer service, it just feels that they're trying to fix your problem when something doesn't work out (e.g. when you don't get the food in time, etc.).
Yes, it excels at synchronization, you could just put a server synchronized and you have your backup, or let each user of an application have his own server which is synchronized with others (e.g., for a smart lock system). That's something pretty useful for privacy or if you have connectivity problems like in a mesh network with interruptions.

For the app itself, its really about getting end-to-end encryption be able to use the app while offline without loosing data.
How to copywrite like Eddie Schleyner
I hear you on the pricing. This is probably something you'll do once or twice a day if you make a routine out of it. I intend to get the prices down at scale, but when you put it against other consumer products (RXbar, starbucks coffee, etc) it turns out to be not so bad.

30s (maximum) vs 5 minutes (minimum) - I think you'd get it after you sat down and tried it. I'm getting feedback that it is a dealbreaker and why my product is superior. In an A/B test, people literally gave up on the pills because they got bored. Imagine what 5 minutes means if you're rushing to get to work.

Natural - It's all about marketing. While you are right, that's not what 99% of Americans believe and they all specifically search for natural products. The fact that this odd effect comes from a fruit I think is important because it is perceived safer than if it was a synthetic compound causing these taste changes.
